| Research Abstract |
In this work, we have succeeded in the development of self-propagating exothermic structure. The structure consisted of Ni-coated Al nano-particles. By inducing a small spark at the vicinity of the structure, NiAl intermetallic compound could be produced with exothermic reaction. By using the reaction, SnAg solder film was melted, and solder bonding of Si chips in very short time period could be achieved.
